2. Pump Description
The Davey Peristaltic pump is characterised by its ability to measure pH
value (between 0 and 14) with its probe placed on the filtration system
that analyses the pool water.
Depending of the measured value, the pump will inject the required
amount of product needed to maintain the balance of the pool water.
The pump works in acid (pH-) or basic (pH+) dosage.
